THE CONTRIBUTION OF SURFACE CHARACTERS TO THE WETTABILITY OF LEAVES

Authors


Abstract

A method of preparing carnauba wax positive replicas of leaf surfaces is described and these have been used with other techniques to study some of the factors which govern the wetting of leaves by water. Leaves from four species of plants were used. It was found that macroscopic surface roughness was the chief factor preventing the wetting of Festuca pratensis. The contribution of surface chemistry and surface roughness is discussed also for results obtained with leaves of Agropyron repens and two species of Papaver.
